Abstract We compared DXA whole body and lumbar spine bone mineral density (BMD) using manufacturers software with a body size correction which derived bone mineral content (BMC) for bone area in survivors of acute lymphoblastic leukemia in Saudi Arabia (n = 51, mean age 13.5 y). With no corrections, 29 patients (57\%) had lumbar spine BMD Z score < -1.0 and 21 (41\%) had whole body BMD Z score < -2. After correction, only 6 (12\%) had lumbar spine BMC Z score < -1.0 and 4 (8\%) had whole body BMC Z score < -2. Agreement between the methods was "poor" by weighted κ analysis.
